That's sad it's not turning on for you sharonda1967 but I want to try to help you out. There is a way to force the tablet to reboot. You'll want to try holding down the power button for about 10-15 seconds to see if it kick starts. You could also try powering it up when it's plugged into a charger. If you still need some assistance, Contact Us and speak with Tech Support. They'll have the ability to check the warranty and provide next steps to help you further.
